DUMPlNG-WAGON.

SPECEFCATION formingpart of Letters Patent No. 719,533, dated February3, 1903.

Application iiled August 26. 1902. Serial No. 121,087. (No model.)

T 0 LZZ whom, t may concern/ Y Beit known that I, JAMEs THOMPSON, acitizen of the United States, residing at Greeley, in the county of Weldand State of Colorado, have invented certain new and useful Improvementsin Dumping-Wagons; and I do declare the following to be a full, clear,and exact description of theinvention, such as will enable othersskilled in the art to which it appertains to make and use the saine. 4This invention relates to improvements in dumping-wagons, andparticularly to those which dump or discharge their load at the sides.

The object of the invention is to construct a wagon of this character bywhich the body of the same may be readily moved laterally across thewagon-bed to either side and allowed to tilt and discharge its contents,the sides of the wagon being adapted to be low ered when the body of thewagon is so tilted to allow the load to slide out.

A further object is to produce such a wagon which shall be simple ofconstruction, durable in use, easy to operate, and comparativelyinexpensive of production.

With the above and other objects in view, which will readily appear asthe nature of the invention is better understood, said inventionconsists in certain novel features of construction and combination andarrangement of parts,which will be hereinafter fully described andclaimed,andillustrated in theaccompan ying drawings, in which- Figure 1is a longitudinal vertical section through a wagon, showing theapplication of my invention. Fig. 2 is a rear-end elevation of the same.Fig. 3 is a similar view showing the parts in their tilted or d umpedposition. Fig. 4. is a transverse vertical section on line 4 i of Fig.l, and Fig. 5 is a top plan view of the wagon-bed. y

In the drawings, l denotes the wagon-bed, and 2 denotes the wagon-body.

3 denotes the supporting-wheels.

The wagon-bed consists of the longitudinally-disposed side bars 4,supported upon bolsters carried by the axles, as usual. 5 denotescross-bars connecting the said side bars, said cross-bars being formedof parallel strips, and on the top of the outer strip of each endcross-bar is fixed a rack-bar 6, extending across the width of thewagon-bed. The purpose of said bar will hereinafter appeal'. Between theparallel strips of the said cross-bars are journaled antifrictionbearing-rollers 7 upon which the sills 8 of the wagon-body are adaptedto rest and slide. The rollers 7 are so journaled and are of suchdiameter that they will be below the upper edges of the parallel stripsof the cross-bars, andthe sills 8 of the wagon-body are of such width asto readily fit and slide between the said strips, this constructione'tfectually preventing any forward, rearward, or twisting movement ofthe wagon-body and consequent slipping oi'l of the sills 8 from therollers 7.

9 denotes a central longitudinally-disposed shaft journaled in the sills8 immediately below the oor of the wagon-body. The ends of the saidshaft project beyond the end crossbars and are provided with flangedcog-pinions 10, which are adapted to engage the rackbars 6. The rear endof the shaft 9 is extended beyond the rear pinion and is squared toreceive a crank l2, whereby the said shaft is rotated.

13 denotes laterally-projecting hooks fixed at the ends and upon the topof the strips forming the cross-bars 5 and are adapted to engage theshaft 9 when the wagon-body has been shifted to one side of the bed andforming a bearing or rest for said shaft and allowing the wagon-body totilt thereon, the tilting movement of the wagon-body beinglimited bychains 14,0ne end of each of which is connected to some part of thewagon-bed and the opposite ends of which are provided with hooks fordetachably connecting the same with the sills of the wagon, there beingpreferably four of such chains, one at each corner of the wagon, thechains also serving, when hooked up at both sides, to prevent the bodyof the wagon from running over to one or the other side of the wagon-bedwhen the same is tilted by reason of inclined roadway or other causes,it being necessary to unhook the chains on the side of the wagon to bedumped before that operation can take place, as will be seen byreference to Fig. 2 of the drawings.

15 denotes the sides ot the wagon-body, which are hinged at their loweredges to the ends of the sills 8 and are adapted to swing downwardly andoutwardly on a line with the IOO floor of the wagon. The sides arebraced by vertical standards 16, the lower ends of which when the sidesare opened are adapted to abut against the outside longitudinal bars 8,connecting the sills S, and thus support the sides l5 in their open'position.

17 denotes hooks pivoted to the ends of the wagon-body and adapted toengage the sides thereof When the same are raised to hold them firmly inthis position.

In operation when it is desired to dump the Wagon to discharge a loadthe crank is` applied to the rear end of the shaft 9, and said shaft andthe pinions l0 carried thereby are rotated in one direction or theother, said operation causing the pinions 10 to engage the teeth of t-herack-bars 6, and thereby move said wagon-body laterally to one side orthe other of the wagon-bed until the outer side overbalances the innerside, which occurs at or about the time that the shaft 9 reaches hooks17, at which time the wagon-body will be caused to tilt, it beingunderstood that the chains 14E have been previously unhooked on the sideof the wagon to be dumped. The side of the wagon now being swung down-Wardly and outwardly, as shown in Fig. 3 of the drawings, the contentsof the wagon will be discharged. Movement of the crank in an oppositedirection will restore the Wagonbody to a horizontal position, andfurther retrograde movement of the crank and shaft will draw the saidbody back over thewagonbed again to its normal position.

From the foregoing description, taken in connection with theaccompanying drawings,

nasse it is thought that the construction, mode of operation, andadvantages o f my improved dumpingwagon will be readily apparent withoutrequiring a more extended explanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecu re by Letters Patent, is-

In a du mping-wagon, the combination with a wagon-bed, of a wagon-bodycarried by said bed, outwardly and downwardly swinging sides hinged tosaid body, a longitudinallydisposed shaft carried by said body, flangedcog-pinions carried by said shaft, rack-bars carried by said wagon-bedand adapted to be engaged by said cog-pinions, means for rotating saidshaft and pinions to move said body laterally in either direction acrosssaid bed and tilt the same, antifriction rollers for supporting saidbody, guideways to prevent front or rear movement of the same, and meansfor supporting said body in its tilted position, substantially as andfor the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
